Russian and US warships have been in friction again a few days ago. Russia said it had expelled a US destroyer that had entered Russian territorial waters, while the US side said it was sailing in international waters and had not been expelled from the territorial waters of any country. Recently, the U.S. government officially withdrew from the open sky treaty, and at the same time took a negative attitude towards the renewal of the New Strategic Arms Reduction Treaty (start) and had friction with Russia at sea. These actions reflect the trend of intensified Military game between the two countries. Russian and us analysts believe that from the standpoint of US President-elect Biden and his team, the future of Russia US relations, which continues to hover at the freezing point, is not optimistic. The Russian Ministry of Defense said on the 24th that the US Navy Destroyer “John McCain” entered the waters near the Gulf of Peter the great in Russian territorial waters on the same day and crossed “two kilometers” of Russian territorial sea line. The Russian anti submarine Destroyer “admiral Vinogradov” issued a warning to the “John McCain” and said it might collide with it. “John McCain” immediately left Russian territorial waters. The U.S. Navy’s Seventh Fleet said in a statement on the 24th that the “John McCain” was carrying out “freedom of navigation” in international waters and had not been expelled from the territorial waters of any country. The US media said that the US Navy’s operation in the Gulf of Peter the great is very rare. General Kravchenko, former chief of general staff of the Russian navy, believed that the “John McCain” was obviously carrying out reconnaissance activities. The president of Russia’s geopolitical research institute, sivkov, said that the “John McCain” may try to induce the Russian side to attack and target it in order to spy on the operation of Russian ships. In recent years, there has been constant friction between the Russian and American armies. Military vehicles of the two sides collided in Northeast Syria in August this year, injuring four U.S. personnel. In December 2018, the U.S. Navy Destroyer “mccambel” sailed into the waters near Russia’s Peter Great Bay, and Russia said the act was “provocative and demonstrative”. < p > < p > military frictions reflect the current situation of tense relations between Russia and the United States. Since U.S. President Trump came to power, the relations between the two countries have been at an impasse. According to Russian officials, the current Russian US relations are at the lowest point in history, and the high-level dialogue between the two sides has in fact been interrupted. According to koltonov, director of the International Affairs Council of Russia, a think tank, Trump’s commitment to repair bilateral relations has never been fulfilled. The four years since 2016 have been four years of rapid deterioration in Russian US relations. On the 22nd of this month, the U.S. government announced its formal withdrawal from the open sky treaty, which was signed by the United States, Russia and most NATO countries. Since the 1970s, the arms control treaty has been the core pillar of the relationship between the United States and the Soviet Union, and the “open sky treaty” is a successful case of “cooperative monitoring” in the field of arms control. The withdrawal of the United States from the treaty is seen as another blow to the already fragile relationship between the United States and Russia. As the U.S. government is about to change, U.S. and Russian analysts expect that bilateral relations will remain difficult to improve in the future. U.S. analysts generally believe that President-elect Biden will take a tough stance on Russia after taking office, and the tension between the two countries will continue. Biden himself said in an interview with CBS in October that Russia’s destruction of the U.S. security and alliance system is the “greatest threat” to the United States at present. Antony brinklin, the Secretary of state candidate announced by Biden, had criticized trump for being “too weak” to Putin and advocated taking a strong stand against Russia. However, Jack Sullivan, an assistant candidate for National Security Affairs announced by Biden, once supported the supply of anti tank missiles to Ukraine to deal with Russia during the Ukraine crisis. Russian officials and scholars are not optimistic about the trend of Russia US relations after Biden took office. Slotsky, chairman of the International Affairs Committee of the Russian State Duma, believes that the relations between Russia and the United States will not improve after Biden takes office, because at that time, it will be those who have served in the Obama administration who regard Russia as the enemy of the United States. Former Russian Foreign Minister Ivanov said that many people in Russia are worried that Biden may take a tougher stance against Russia and expand the already severe sanctions against Russia.
